My husband is a smoker and is a heavy coffee drinker. I even use it on my dentures. We have noticed a great improvement over the last week. Our teeth have never been whiter.

I started using this product about a month ago and im happy to say that it really works! It has make my teeths whiter by just one week exactly. And the more I use it the more whiter my smile gets. I truly recommend this product.

The description clearly states 10 pack, where is the confusion that I was sent a 2 pack and paid $15 for 2 tubes of toothpaste!!! Ridiculous!!!!!!!!!!!! Will be returning for sure, fix your description!!!!

I am 63 and my teeth have some yellowing so I tried this product for 1 month and it did nothing at all to my teeth. I will keep using it cuz I have a full tube but I am not counting on any change.

This is the second tube of Optic White I have used. I would consider I have given it a fair trial. My teeth are no different from the day I purchased the first tube. I would consider Optic White to be absolutely useless in whitening teeth.

I took a bunch of selfies the other day & noticed my teeth were a lil bit whiter! I use it 2x a day & use a straw for colored beverages, rinse w/h20 after meals.

The tube is the worst I have ever tried to use. Messy and Wasteful! Why? What is the problem with using your regular style Colgate Toothpaste tube?

There was less than half a tube of toothpaste in the new tube! What a waste of money. Won't buy that again.

I was not expecting such great results. WOW!!!

I brush twice a day everyday and it works.
